Is there a way to get the audio files of those not well mastered CDs
into your DAW, tweak them with EQ etc, and get rid of the harshness in
their sound? For example, I re-discovered an old favorite CD,
SuperTramp's Brother Where You Bound. I used to listen to it allot on my
cassette made from the CD. Obviously, recording to cassette did allot to
qwell it's high end harshness. My cassette deck has long since been
retired and I'd like to listen to and enjoy the CD now. When listening,
there's that high-midrange sound, I guess you might describe it as some
digital filter used in the mastering process that produced allot of
audible ringing.

I've transferred the audio data to my DAW and I'm ready to fire up Cool
Edit to tweak the files. Any suggestions?

TIA
